When a thread (operating system) tries to obtain a lower-level mutex that it does not already hold but is unable to find, it displays the MUTEX_LEVEL_NUMBER_VIOLATION blue screen of death error with a bug check value of 0x0000000D. Though it rarely appears in Windows, troubleshooting the MUTEX_LEVEL_NUMBER_VIOLATION BSOD issue is more challenging. Let’s go right to it, then!
